New Delhi: A 19-year-old pizza delivery agent who had tested positive for COVID-19 last month in Delhi, prompting authorities to order home-quarantine for 72 families, has been discharged from the hospital, officials said on Tuesday.

All 16 high-risk contacts of the delivery boy had tested negative in April. They are colleagues of the delivery agent.

"The pizza delivery agent was discharged from the hospital last week. He is doing fine now," South Delhi district magistrate BM Mishra told PTI.

The delivery agent had tested positive for the virus on April 14 and thereafter, the district administration had decided to put 72 families he delivered pizzas to in south Delhi under home-quarantine.

The district administration had not conducted COVID-19 test on the members of these families as they had not shown any symptoms of the infection.

Thirteen deaths and 406 new COVID-19 cases have been reported in Delhi, taking the toll to 86 and tally to 7,639, according to a health bulletin released by the Delhi government on Tuesday.
